EigureTis-a cross-sectional view taken on line 7-7 oiiill igurefii v The-lock casing disclosed being of circular formcompris'es a bottom wall 1, an annular. side wall 2. and a cover wall 3 secured to theannular side wall 2 by the rivet bolt 4, the annular side ,wall 2 ot the lock casing beingprovided'with openings for the ,pas- *sageof-the relatively short and long legs 6 and'Trespectively of the shackle 8. The annularside wall 2 of the lock casing is provided with three slotted openings 9,- 10 and .11 for the passage of tumbler operat- 'iing handles to be presently described, while 1928; Serial No. 293,922.

theopposite SldOf the wall 2 upon its inner face carries a block 12 grooved iorrthe passage of the shackle leg? that has" atnotch 13 therein to be aligned with the vertical slot i l-in the block 12 to receive the locking pin of the lock mechanism for retaining. the shackle locked in the casing.

The detailed construction of the lock mechanism comprising a plurality of disk tumblers and operating handles together with a sliding tumbler plate and a locking pin for the shackle, which is shown more clearly in Figure 3, the tumbler plate 15 having a slotted opening 16 therein received on the bolt 4: and is slidably mounted upon the bottom wall 1 of the lock casing. asshown in Figures 5 and 7, the tumbler plate. 15 being further. guided in its sliding movement by the pin 17 positioned between the forked end 18- of the tumblers plate A perpendicular locking pin 19 is carried by the sliding tumbler plate 15 and is adapted to be moved into the registeringnotch and slot. 13 and 14 formed respectively in the shackle leg 7 and locking block 12. The sliding; tumbler plate-15is normally influenced in a direction away irom the block 12 by the leaf spring 20 anchored at one end as at 21 to the inner face of the annularside wall of the lockcasingrwith the free end thereof selectively positioned in the desired notch 22 formed in the adjacent edge of the tumbler plate 15, the springerrd beingiretained in position inxthe notch by 'the upper" guide finger 23 carried by thebottom wall of the lock casing The series voi disk tumblers comprises a tumbler disk 24c'having a central opening.v 25' received on the casing bolt 4 and a peripheral. notch 26 of a size to receive the locking pin 19, the tumbler disk 24L carrying a. radial handle 27 extending through the slotted opening,9 in the side wall of the lock casing with the outer end thereof bent as'at 28. The in ner end of the handle 27 adjacent the tumbler disk 24 is provided with a shoulder 29 forming a tumbler lug'engageable with a tumbler lug upon another disk tumbler. The tumbler disk 30-havingthe central opening '31 isthen placed on the bolt 4 and has aperipheralnotch-32 to receive the locking pin 19 and .105- also a pair ofspaced depending tumbler lugs 33 an'd34. The tumbler disk 35 having the central opening 36 and peripheral notch 37 is mounted upon the bolt l'engagedwith the tumbler disk 30 and also has a tumbler lug 1101 engaging shoulder 38 at its point of connection with the operating handle 39 that extends through the slotted opening 10 in the side wall ofthe casing. The tumbler disk 40 1s mounted upon the tumbler disk and has a central opening 41 to accommodate its mounting and also a peripheral notch 42. An upstanding tumbler lug 43 is carr ed by the peripheral edge of the tumbler disk which also carries a depending tumbler lug 44. The tumbler disk 45 having the central opening 46 and peripheral notch 47 is mount ed upon the bolt 4 contacting the tumbler disk 40 and carries a handle 48 extend ng through the slotted opening 11 of the casing with the outer end thereoi bent as at 49. A top tumbler disk 50 having the central opening 51 is mounted upon the upper end oi the bolt 4 and has a peripheral notch 52 and a depending tumbler lug 53. A washer 54 1s mountedupon the upper end of the bolt beneath the cover 3 and retains the several tumbler disks engaged with each other.

lVhen the several tumbler disks have been positioned to dispose all of the peripheral notches therein in alignment with the locking 7 pin 19, the spring 20 moves the locking pin and sliding tumbler plate 15 to position the pin in said notches as shown in Figure 6 and when it is desired to move the locking pin into the notch 13 and slot 14 in the shackle leg 7 and block 12 respectively, the lever 54 which is pivoted as at 55 in the casing with the operating end 56 thereof extending through a wall slot is operated to cause the end 57 thereof to engage the inner end of the tumbler plate 15 to move the same against the tension of the spring 20.

When it is desired to release the shackle from the locked position shown in Figure 4 and in which position the several 'disk tumblers are disposed so that the peripheral notches thereof are displaced from alignment with the locking pin 19, the several handles 27, 39 and 48 are moved to the lower ends of the slots 9, 10 and 11 as shown in Figure 4. The handle 48 is first moved through the full length of the slot to the upper end thereof without operating any of the other tumbler disks. During such movement, the notch 47 in the tumbler disk 45 carrying the handle 48 is moved slightly beyond the locking pin 19. The handle 39 is then moved to the upper end of the slot 10 and the shoulder lug 38 carried by the tumbler disk 35 engages the depending lug 44 upon the tumbler disk 40 to move said 'disk, while the upstanding tumbler lug 43 011 the tumbler disk 40 positions the edge notches 42 and 52 upon the tumbler disks 40 and 50 respectively in alignment with the locking pin 19. The handle 48 is then moved through the slot 11 to the point 58 for positioning the notch 47' in alignment with the locking pin 19. l/Vhen the handle 27 was first placed at the lower end of the slot 11, the same engaged the lug 33 upon the tumbler disk 30 to position the notch 32 in alignment with the looking pin with the notch 26 in the tumbler 'disk 24 slightly moved upwardly beyond the looking pin. The handle 27 is finally raised to the point 59 to dispose the edge notch 26 in alignment with the pin and at which time the several notches in the tumbler disks are aligned and receive the locking pin 19 that is shifted by the spring 20. With the locking pin displaced from notch 13 in the shackle leg 7, the shackle leg is permitted to be moved outwardly of the casing a limited distance as illustrated in Figure 6 to effect the release of the shackle. The locking pin 19 is restored to locking position by the lever 54 in a manner previously described.

From the above detailed description of the invention, it is believed that the construction and operation will at once-be apparent, and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
